Description
Technical field
The present invention relates to is the continuous cyclone clarification treatment device of a kind of finishing apparatus of electroplating wastewater, especially electroplating wastewater.
Background technology
At present for the electroplating enterprise of middle and small scale, because its waste water water yield is little, water quantity and quality changes greatly, the material recovery value in the waste water is not high, its cost-effective treatment process remains chemical precipitation method.Traditional chemical method treatment process mainly comprises pre-treatment, aftertreatment, sludge dewatering three parts, wherein tube settling and sand filtration are mostly adopted in aftertreatment, though this technical process is simple, go up detective, settling tank, sand filter floor space are big, sand filter back flushing difficulty.And, often contain tensio-active agent in the electroplating wastewater and electroplate solvent, the chemical oxygen demand (COD) (COD in the waste water
Cr) be 180～260mg/L, traditional aftertreatment technology is owing to lack chemical oxygen demand (COD) (COD
Cr) effective technology of removing causes water outlet COD
CrOften do not reach integrated wastewater discharge standard.Therefore be not suitable for the wastewater treatment of middle and small scale electroplating enterprise.
Summary of the invention
The purpose of this invention is to provide and a kind ofly will precipitate, filter, clarify in the continuous cyclone clarification treatment device of the electroplating wastewater of one.
The continuous cyclone clarification treatment device of electroplating wastewater of the present invention, comprise housing, in housing from inside to outside successively coaxial line be equipped with inner core, ring washer and little down big conically shaped, the hypomere of inner core is a cylindrical tube, the epimere barrel dliameter is expanded gradually and is horn-like formation reaction chamber, lower end at inner core has return port, water inlet pipe stretches into housing and is communicated with the inner core lower end is tangent, space between inner core and the ring washer constitutes the mud circular chamber, the big end of conically shaped circumferentially links to each other with the inwall of housing, the small end of conically shaped circumferentially links to each other with the junction of ring washer and housing bottom, the cavity that conically shaped outer wall and housing form is a water purifying chamber, the inwall of conically shaped and the space between the ring washer constitute mud-collecting slot, water purifying chamber is provided with rising pipe and draws housing, mud-collecting slot is provided with shore pipe and draws housing, coaxial line is with tube outside the reaction chamber of inner core, be fixed with upper annular plate and lower annular plate and form the sludge settling chamber between the outer wall of tube and the inwall of housing, this exceeds the hydraucone and the upper annular plate of reaction chamber, on the lower annular plate around circumferentially porose be arranged in the sludge settling chamber in inclined tube communicate, above inclined tube, be provided with the foam bead filtering layer, water outlet is arranged on the upper annular plate, water outlet is provided with the filter cap, in the space that upper annular plate and drum outer wall and inner walls surround, around the inner walls device overflow groove is arranged, an end of the pure water pipe that communicates with overflow groove inserts in the water purifying chamber.
During apparatus of the present invention operation, add polyacrylamide (PAM) at electroplating wastewater, electroplating wastewater enters the inner core from tangential direction through water inlet pipe, electroplating wastewater is along mixing with PAM fast and equably in the inner core rotation process upwards, produce the whirlpool body, for tiny heavy metal hydroxide throw out provides good flocculating conditions, improved flocculating effect and shortened flocculation time.
After current quickened to arrive reaction chamber along the inner core rotation, because the diameter of reaction chamber enlarges gradually, flow velocity reduced, and flco is grown up gradually, and flow velocity slows down after water overflows the inner core hydraucone, and the residence time increases, and impels to form big flco rapid precipitation.
Because the residence time increases, the particle that portion size is bigger directly sinks to the mud circular chamber between inner core and the ring washer, and after current filter through the tube settling of sludge settling chamber and foam bead filtering layer again, mud sinks in the mud-collecting slot along inclined tube, excrete from shore pipe by hydrostaticpressure, clear water flows into the overflow groove after the filter cap comes out, and arrives in the water purifying chamber by pure water pipe, discharges from water outlet at last.
Owing to form cyclone reaction in inner core, the bottom negative pressuren zone can suck inner core from return port with the mud of mud circular chamber, circulates.Because mud has bigger specific surface, adopt clarification process that it is circulated, utilize its adsorption surface can remove COD in the waste water effectively
Cr
The present invention is integrated in eddy flow mixing, clarification, precipitation, filtration, organic the combining together of mud circulation of electroplating wastewater aftertreatment in the device and finishes.This device has little, the COD of floor space
CrAdvantage such as clearance height, effluent quality be good, can dynamically handle continuously, test shows: for total chromium, total copper, total cyanide concentration be respectively 6.72,18.40, the electroplating wastewater of 22.10mg/L after this device is handled, total chromium of water outlet, always copper, total cyanide clearance reach 93.3%, 97.4%, 99.9% respectively.Waste water COD
CrFrom about initial 240mg/L, reduce to about 60mg/L through behind the cyclone clarification.This device is adapted at applying in the micromidi electric plating corporation.
